The interface between a dielectric medium having relative permittivity 4 and free space is marked by the y=0 plane. If the electric field in the free space region is given by E=5ax + 12ay + az V/m, determine the electric field on the other side of the interface.

Charge of uniform surface density 8.00 $\mathrm{nC} / \mathrm{m}^{2}$ is distributed over an entire $x y$ plane; charge of uniform surface density 3.00 $\mathrm{nClm}^{2}$ is distributed over the parallel plane defined by $z=2.00 \mathrm{m}$ . Determine the magnitude of the electric field at any point having a $z$ coordinate of $(\mathrm{a}) 1.00 \mathrm{m}$ and $(\mathrm{b}) 3.00 \mathrm{m} .$
